You’re entitled to use your data however you like, no matter which of the SMARTY plans you're on, so you can tether and use your phone as a mobile hot spot with your full allowance if you want to.
If you're unable to tether or hotspot from your SMARTY SIM, try updating your software to see if there's a later software version that will start it working again.
If you're having problems accessing the internet on your phone after seeing a warning message about Personal Hotspot, just turn your phone off and back on again. If this doesn’t fix the issue, do get in touch with us on web-chat for help.
Note: If you’re travelling in the EU, you will be subject to our fair use limit of 20GB each month.
